testWinProp

Run the programs again to produce the simulation results.

• Simulation goal: simulate the channel variations and received power variations due to impacts of moving objects or moving RXs.

• Environment settings: MSVC(VS 2019) + Clion 2021 + WinProp API 2021 for windows. Use CMakeLists.txt to compile the project.

• Two simulation schemes:
  • Time variant prediction.
    • Can only add time-variant components in .idb
    • Generate the prediction result on the whole “map” at each time instance.
  • Trajectory prediction.
    • Could use C++ command to control.
    • Generate the prediction result along the trajectory.

• Simulation scenarios:

  	Indoor	Outdoor (Urban)
  Trajectory	indoor_trajectory.cpp	outdoor_trajectory.cpp
  Time variant	indoor_time_variant.cpp	Not completed yet (Treated as indoor.)
  Ray-Tracing	SRT	SRT & DPM & IRT

• Go to test_database to see designed databases in this project.

• Simulation settings:

  	TX (10W)	RX	Ray-Tracing	Specifications	Prediction Height
  indoor_trajectory.cpp	omni, 1.25m, 2000 MHz	omni, 1.25m	SRT	1m/s RX	1.25m
  indoor_time_variant.cpp	omni, 1.25m, 2000 MHz	omni, 1.25m	SRT	1m/s Moving Object	1.25m
  outdoor_trajectory.cpp	omni, 15m, 2000 MHz	omni, 1.5m	DPM, SRT (Treated as indoor), IRT (Preprocess the database)	10m/s moving RX	1.5m
  Time variant scenario in outdoor (Not completed yet.)

We could import the exported data into MATLAB to do further processing.

• Remaining problems:
  • Time-variant scenario in outdoor (urban) database.
  • Add directional antenna to RX.
  • Material settings. See ./data/test_database/记录.md.
